provement in Rolling Shutters, of which the following is a specification.

This invention relates to rolling metal shut ters, and is particularly designed to improve the form of shutter shown in the patent to Peter Ebner, No. 655,965, dated August 14, 1900. It is furthermore designed to improve the flexible joint between adjacent shuttor-sections whereby the joint is rendered I 5 stronger and stiifer without interfering with the free and unrestricted hingemovement thereof, and said joint is also adapted to shed water, thereby to obviate rusting thereof, and hence materially increase the life of the shutter.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be herein: after described, shown in the accompanying z 5 drawings, and particularly pointed out in the appended claims.

In the drawings there has been shown asectional perspective view of a rolling metal shut- 'ter embodying the features of the present 0 invention.

The present form of shutter, like all of the rolling type, is made up of a series of slat-sections 1, each of which is substantially oblong in shape and of convolute or corrugated form. 5 One longitudinal edge of each shutter-section, preferably the lower edge thereof, is bent into a substantially circular or cylindrical tube or head 2, which is disposed substantially equally at opposite sides of the longituv 0 dinal plane of the section, with the free edge of the section terminated short of the bodyportion thereof, so as to render the tube sub- 'stantially hook-shaped in cross-section, and thereby form a longitudinal entrance slot or opening 3 along the top of the tube, as best shown in Figure 2 of the drawings. The other and upper edge of the slat or section is bent to form a hook 4, the bill portion 5 of which is upon the opposite side of the slat from that of the free edge portion of the tube 2 and is adapted to be hooked into the lower hooked j entering the hinged joint.

end portion of the nextabove section, "as

clearly shown in Fig. 1 of the drawings. It will of course be understood that one section is slid endwise into engagement with the other instead of having its hooked edge passed through the slot 3 of the other section. At the outer extremity of the bill portion 5 of the hook 4 the slat is bent into a complete tube or bead 6, which is disposed at the outer side of the bill, whereby the latter lies between the bead and the body of the slat. Furthermore, this bead is located in a position comparatively remote from the bend portion 7 of the hook 4 and bears against the lower portion of the hook portion 2 of the adjacent slat or section, whereby each slat has a hearing at two points upon the next-above slatthat is to say, the stifiening-bead 6 bears against the interior of the hook 2 at the bottom thereof,

and its bend portion 7 bears against and hangsupon the free edge portion of said hook 2.

From the foregoing description it is apparent that by having the bead 6 remote from the bend portion 7 of the hook-4, so as to bear against the bottom of the hook 2, said hook 4 is materially stifiened and strengthened and the joint is rendered very strong and durable without interfering with the free and unrestricted hinge movement thereof. Furthermore, by having the hook 2 disposed equally at opposite sides of the plane of the slat-section the-convolute intermediate portion of v the slat overhangs the slot 3, and thereby forms a water-shed to direct water laterally outward, and therebyprevent the same from This is a material feature of the present invention, as it provents rusting of the joint, and hence protects it.

What is claimed is 1. Arollingshutter,embodyingloosely-connected slats, one slat having its edge portion bent into'substantially tubular shape which is disposed substantially equally at opposite sides of the plane of the slat, with the free edge of the slat terminated short of the body of the slat to form a longitudinal slot, the en-- gaging edge of the adjacent slat being bent into the form ofa hook, the bill of which passes through the slot aforementioned, and terminates in a bead remote from the bend of the hook and bearing against the interior of the first-mentioned hook.

2. As a new article of manufacture, a shuttor-slat havingone longitudinal edge bentiuto a substantially circular hook which is disposed substantially equally at opposite sides of the plane of the slat, the opposite edge of the slat being bent into a hook disposed at the opposite side of the plane of the slat,with its bill portion extended toward the firstmentioned edge of the slat and bent into a stifiening-bead disposed at the outer side of the bill and remote from the bend of the hook.

3. A rolling shutter, embodying slat-sections which are of convolute form, the lower edge of each section being bent into a substantially circular hook disposed substantially equally at opposite sides of the plane of the slat with the adjacent convolution overhanging the slot or opening between the free end of the hook and the bodyof the slat, the upper edge of each slat being bent into a hook disposed at the opposite side of the slat with its bill portion passed through the slot of the lower edge of the next-above slat, the bill being extended downwardly and bent into a bead disposed at the outer side of the bill and normally bearing against the inner side of the bottom of the hook of the next lower hook, and the bend of the upper hook hanging upon the free end of the lower hook.
